Abstract/OtherAbstract:
|
An experimental investigation has been conducted into the effects of electrostatic charge, carried by the dust particles and by the sampler itself, on the sampling of airborne dusts. Experiments covering both personal and static sampling and a range of sampler types were carried out in the laboratory for both fibrous asbestos and isometric silica gel dusts. Experiments also were carried out in the spinning shop of an asbestos textile factory. The results showed that the aspiration efficiency of the sampler always is reduced as the charge on the sampler increases, independently of the type of sampler and of whether it is used as a static or personal sampler. The effect is most marked when sampling takes place in calm air. It is concluded from the results that, for the levels of charge reached by samplers in most practical situations, the effects on aspiration efficiency will be small. Possible exceptions to this might occur, however, in workplace environments where relative humidity is very low, and charge levels of the sampler (or on the worker wearing the sampler) can become high. |
